The night sky is changing, and travellers may already have noticed it. What once looked like a quiet field of stars is now increasingly crossed by moving points of light. These are satellites from projects such as SpaceX’s Starlink network. Since the first launch in 2019, their numbers have grown quickly. For those who travel to remote places to enjoy nature and stargazing, this shift is becoming harder to ignore.
Starlink is a system of satellites designed to provide internet access from space. Instead of relying on cables in the ground, the network sends signals from satellites orbiting Earth down to small dishes on the surface. This makes it possible to connect areas that are far away or difficult to reach, such as rural regions or islands. The system can also be set up quickly, which has made it useful in emergencies and natural disasters. For isolated communities, this technology has improved access to communication, education, and services.
As of late 2025, there were already more than 9,000 Starlink satellites in orbit, with most of them actively working. Each satellite stays in space for around five years before being replaced. In the long term, the company hopes to expand the network to tens of thousands of satellites. There are proposals under review to increase that number dramatically, potentially reaching up to one million satellites in the near future.
For travellers, the most visible impact is in the night sky itself. Starlink satellites orbit relatively close to Earth and can often be seen without special equipment. They sometimes appear as a line or “train” of lights moving together across the sky. In places known for their dark skies, these lights can disrupt the natural view that visitors travel long distances to experience.

Stargazing tourism has grown in recent years, with many destinations promoting clear, unpolluted skies. People visit deserts, mountains, and protected parks to see the Milky Way and thousands of stars. However, studies suggest that with tens of thousands of satellites, a noticeable part of the night sky could be filled with artificial objects. In more extreme scenarios, scientists warn that satellites could even outnumber visible stars. This would change the experience of the night sky for travellers around the world.
Astronomers are also raising concerns about the impact on scientific research. Organisations such as the International Astronomical Union have warned that large satellite constellations can interfere with observations. Bright satellites can leave streaks in telescope images, making it harder to study distant objects in space. Radio signals from satellites may also affect radio astronomy, which relies on very quiet frequencies to detect signals from the universe. These challenges are becoming more frequent as the number of satellites increases.
Beyond astronomy, there are environmental and safety questions. The growing number of satellites increases the risk of collisions in orbit, which could create debris and make space operations more dangerous. When satellites reach the end of their life, they burn up in the atmosphere. Scientists are studying whether this process could affect the atmosphere over time, especially as more satellites are launched and replaced. There are also concerns that increased brightness in the night sky could affect wildlife that depends on natural darkness.
Private companies are playing a larger role in the rapid growth of satellites than ever before, alongside national space agencies. Firms like Blue Origin are also developing new technologies and expanding access to space. At the same time, interest in space tourism is rising, with more people travelling to witness launches or even experience spaceflight. As activity in space increases, so does the number of objects orbiting Earth.
For now, the future of large satellite constellations is still being discussed. Proposals for major expansions are under review by regulators, and scientists are calling for more studies on their impact. Companies have started to test ways to reduce brightness, such as adding visors to satellites. The challenge will be finding a balance between improving global connectivity and protecting the night sky.
